Summary

libarchive security update

Details

is an open-source BSD-licensed C programming library that provides streaming access to a variety of different archive formats, including tar, cpio, pax, zip, and ISO9660 images. The distribution also includes bsdtar and bsdcpio, full-featured implementations of tar and cpio that use .

Security Fix(es):

Incorrect link resolution flaws can occur when extracting archives, resulting in changes to the mode, time, access control list, and flags of files outside the archive. An attacker could deliver malicious archives to victim users, triggering this vulnerability when they attempt to extract the archives. A local attacker could exploit this vulnerability to gain additional privileges on the system.(CVE-2021-31566)

Incorrect link resolution flaws when using ACLs to extract symbolic links can lead to changes to the access control list (ACL) of the link target. An attacker could deliver malicious archives to victim users, triggering this vulnerability when they attempt to extract the archives. A local attacker could exploit this vulnerability to change the ACL of a file on the system and gain more permissions.(CVE-2021-23177)

Severity

6.6 (Medium)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
